How to get List of Data in Tabbed Actvity?

I have made a program in which i am fetching list of all my Facebook Friends with their name, dob and profile picture, but i have decided to use tabs in my existing program therefore, i have also written code for that, but whenever i run my app, every time i am getting tabs but not getting list of friends..

In my case i am not getting FriendsList Activity data in TabSample Class, why?

SplashScreen.java:-

   private final static int FACEBOOK_AUTHORIZE_ACTIVITY_RESULT_CODE = 0;
   private final static int FRIENDS_LIST_ACTIVITY = 1;
   public void onRequestReceived(int result, String message) {
    Log.d(LOG_TAG, "onRequestReceived(" + result + ")");
    if(isFinishing())
        return;
    switch (result) {
    case FacebookRequest.COMPLETED:
        Intent intent = new Intent(this, com.chr.tatu.sample.friendslist.TabSample.class);
        intent.putExtra("FRIENDS", message);
        while (System.currentTimeMillis() - startTime < DELAY) {
            try { Thread.sleep(50); } catch (Exception e) {}
        }
        startActivityForResult(intent, FRIENDS_LIST_ACTIVITY);
        isLoadingFriends = false;
        break;
    case FacebookRequest.IO_EXCEPTION:
    case FacebookRequest.FILE_NOT_FOUND_EXCEPTION:
    case FacebookRequest.MALFORMED_URL_EXCEPTION:
    case FacebookRequest.FACEBOOK_ERROR:
        FacebookUtility.displayMessageBox(this, this.getString(R.string.friends_error));
        onButton();
        break;
    }
}

FriendsList.java:-

TabSample.java:-

    super.onCreate(savedInstanceState);
    setContentView(R.layout.tabmain);
    setTabs() ;

}
private void setTabs()
{
    addTab("All", R.drawable.tab_menu, FriendsList.class);
    addTab("Current Month", R.drawable.tab_offers, FriendsList.class);

    addTab("Current Week", R.drawable.tab_location, FriendsList.class);
    addTab("Today", R.drawable.tab_reservation, FriendsList.class);
}

private void addTab(String labelId, int drawableId, Class<?> c)
{
    TabHost tabHost = getTabHost();
    Intent intent = new Intent(this, c);
    TabHost.TabSpec spec = tabHost.newTabSpec("tab" + labelId); 

    View tabIndicator = LayoutInflater.from(this).inflate(R.layout.tab_indicator, getTabWidget(), false);
    TextView title = (TextView) tabIndicator.findViewById(R.id.title);
    title.setText(labelId);
    ImageView icon = (ImageView) tabIndicator.findViewById(R.id.icon);
    icon.setImageResource(drawableId);

    spec.setIndicator(tabIndicator);
    spec.setContent(intent);
    tabHost.addTab(spec);
}
   }

Please tell me where i have to add this code :

Bundle extras = getIntent().getExtras();
        String response = extras.getString("FRIENDS");

        Log.d(LOG_TAG, "onCreate()" + response);

        try {
            jsonArray = new JSONArray(response);
        } catch (JSONException e) {
            FacebookUtility.displayMessageBox(this, this.getString(R.string.json_failed));
        }

and any other code need to move from FriendsList class to TabSample Class
